Class 4 Dangerous Goods - Flammable Solids; Substances Liable To Spontaneous Combustion; Substances Which Emit Flammable Gases When In Contact With Water

Dangerous Goods which are classed as Flammable Solids are materials which, under conditions encountered in transport, are readily combustible or may cause or contribute to fire through friction, self-reactive substances which are liable to undergo a strongly exothermic reaction or solid desensitised explosives.

Also included are substances which are liable to spontaneous heating under normal transport conditions, or to heating up in contact with air, and are consequently liable to catch fire and substances which emit flammable gases or become spontaneously flammable when in contact with water.


4.1: Flammable solids.

4.2: Substances liable to spontaneous combustion.

4.3: Substances which, in contact with water, emit flammable gases.

Reason for Regulation

Flammable solids are capable of posing serious hazards due to their volatility, combustibility and potential in causing or propagating severe conflagrations.
